Yeah, I'm afraid Daja has taken a dislike to Mei-Xing, and her agreeing to teach her is...not likely. From the sounds of it, I guess Hiccup's not any more likely to either?

But if we ever get any more people learning it though, possibly one of them might be convinced to teach her? Though Mei-Xing would probably end up with a lot of bad habits by learning from a newbie.
